测试实例变量等价（RSpec）

Question

如果之前有人问过，请道歉。我正在尝试使用oop制作游戏策划者。该类的目的是检查两个实例变量（代码和猜测）是否相等。如何设置实例变量以进行测试？谢谢！

class MastermindCodechecker
  def initialize(code, guess)
    @code = code
    @guess = guess
  end

  def check?
    # return true if @code == @guess
  end
end

Answer 1

RSpec.describe 'MastermindCodechecker' do
  describe '#check?' do
    context 'when code and guess are different' do
      @foo = MastermindCodechecker.new('bar', 'baz')

      it 'returns false after check' do
        expect(@foo.check?).to eq false
      end
    end

    context 'when code and guess are equal' do
      @foo = MastermindCodechecker.new('bar', 'bar')

      it 'returns true after check' do
        expect(@foo.check?).to eq true
      end
    end
  end
end
